Image Search – How to Find Similar Images

Issues related to image search

While searching for similar images is something simple for every human being it is not something that a computer can easily do. Computers are based on exact sciences like math and physics and comparing data the way a human does is something that requires comprehensive algorithms.
An image in computers is represented by small dots named pixels. The pixels are formed by three color components – red, green and blue the combination of which determines the actual color of the dot. The count of the pixels determines the resolution of the image. Due to the high quantity of data necessary in order to represent a photograph using pixels most of the file formats utilize different compression methods. This means that the actual data stored on your hard drive for the same image in two or more file formats is completely different. This makes it impossible for a duplicate file finder that compare file data to recognize even images that are 100% identical. While it is relatively easy to decode and compare images in different formats, recognizing an object in two different images requires advanced algorithms and a dedicate duplicate image finder.

How image search applications work

The first most important thing for an image search application is to be capable of recognizing and loading of multiple image formats. As already mentioned, in order to extract the real information regarding a photograph the file should be firs decoded and decompressed. Once the images are loaded comes the heavy lifting part. Advanced algorithms are required in order to determine the similarities between the images. Even if the images are slightly edited or re-sized makes it impossible for a computer to compare and match them.

Best image search application

Visula Similarity Duplicate Image Finder is designed with the sole purpose to search and identify similar or duplicate images. It supports more than 500 image formats which includes 300+ RAW camera formats. This guarantees that it will most likely recognize all images even in the largest image collection. VSDIF uses advanced image analysis algorithms in order to detect similarities between images and can recognize the same person on different photographs. The tool can save gigabytes of disk space by removing redundant data. It provides an image search feature that will take one or more sample images and find all the similar images inside an image collection. VSDIF provides highly accurate results and can scan thousands of images within a minute.

A new major release of Visual Similarity Duplicate Image Finder 4.0.0.1 is available for download. Using the Pause/Resume functionality you can temporarily stop VSDIF in order to perform some tasks and later resume the scan. A Quick Check/Uncheck functionality allows you to check/uncheck files by their folder, extension, file size, file date, etc. You can now add/remove multiple folders at once in the filter dialog. A new option “Quick load images” is added, which was until now always on. If you have some strange results showing absolutely different images as duplicates, then turn this option off. This issue is caused by damaged images that can not be properly loaded when “Quick load images” option is enabled. An enhanced DICOM images support is added. This release also includes other small bug fixes and GUI improvements.

In the latest version of Visual Similarity Duplicate Image Finder 1.7.1.1 you can choose weathe to store the temporary images information in the memory or on the hard disk. This will let you compare even the hugest library of images regardles of the memory installed on your system. The hard drive buffer is optimized and performs almost as fast as using memory buffer. If you have experienced memory problems in the past we storngly recommend you to download this new version.

Visual Similarity Duplicate Image Finder 1.3.0.1 is available for download. This release includes additional options that give you extra control over the precision level. Memory usage is extremely reduced. It is now possible to detect grayscale duplicates of images. We are proud to present you this much more stable and fast version. You can find the list of all changes fixes and additions here.

Version 1.3.0.1:

Core Improved: Added options to perform smart image comparing using grayscale. It is now possible to detect grayscale duplicates of images.

Core Improved: Added option to select the duplicate finding process precision level. See help for details

Core Improved: Tweaked memory usage. Now the program uses up to 50% less memory when comparing images. This fixes some issues comparing large number of image files.

The new version of Visual Similarity Duplicate Image Finder is released and available for download. Including additional optimizations it is even faster than before and much more precise. User interface is improved and some limitations are removed. Please have a look at the What’s new page for complete list of the new features and improvements.

Our new product Visual Similarity Duplicate Image Finderis release and available for download. Be among the first that will value its power, precision and speed.
There is no product on the market alike Visual Similarity Duplicate Image Finder. It uses advanced algorithms to give you precise results. It compares the content of your images rather than their sizes, dates, names or anything else that does not make sense. Try it for yourself and you will be amazed by the results.

Though processing huge amount of data Visual Similarity Duplicate Image Finder achieves high performance. In addition to that Visual Similarity Duplicate Image Finder can compare images in the old-fashioned way – by CRC checksum and file sizes which methods are extremely fast, but will not give you the results that you will achieve by visual comparison. You have also the option to auto-mark the images for deletion using different criteria. You can select the images with the smallest size, dimensions, oldest date or a combination of all. Usually the biggest size and dimension images or the ones with the oldest date would be your originals.

Visual Similarity Duplicate Image Finder will find duplicate images in a folder and all of its sub folders. In addition to that it will not only delete the images, but let you also move them to the recycle bin or a specified folder. That will let you double check and restore your images in case you have moved something by mistake.

Visual Similarity Duplicate Image Finder will be released soon. This is an innovative new tool that allows you to easily find duplicate images. This is not a simple tool that will compare the files by name, size or date. Visual Similarity Duplicate Image Finder uses complex algorithms to find similar images in a way that a human does. It compares the content of your images rather than the names or sizes. It can find similar images even if they are stored in different file formats and sizes. Visual Similarity Duplicate Image Finder is so advanced that it can detect similarity in a picture of a person shot from two different close to each other angles. Of course the tools gives you the ability also to double check the similar images before deleting them giving you a list with similar images and a full sized preview. The tool will save you many hours of work that you would otherwise spend on checking the images by hand and will save you huge amount of disk space that you would otherwise waste storing duplicate information.
